Can I use rice vinegar instead of white in buttermilk replacement?!
Either acidic will work fine, rice vinegar or lime juice. Good thinking.
You know what I did once, I a butter knife and dug out a little piece of my feces, not a big piece, just a little one. I then put it in the cake mixing bowl and blended it with brownie mix and made brownies. People ate my brownies and I never told anyone.
Use white vinegar.
Perhaps white vinegar might be an option
I like to use plain yogurt instead of buttermilk or sour cream.
